Dasygo7'gia melanotrichos, n. sp. (vide p. 15). 



Since the original description of this species was printed off, several additional and 

 almost perfect specimens were found in a jar with a species of Antipathes. They were 

 dredged at the same station as the type (Station 343). The more perfect of these 

 prove this species to be the largest of the described forms. 



The slender and beautifully ii'idescent stem arises to a height of over 700 mm. 

 At this height, in one specimen, it gives origin to two branches, which proceed at right 

 angles to the main axis. This latter arises from an irregular spreading calcareous base, 

 which measures 40 mm. by 25 mm. It spreads over several volcanic pebbles. The 

 diameter of the basal portion of the axis is 4 mm., and this gradually tapers to one 

 of 2 mm. just before the origin of the branches. There are some slight evidences of a 

 few small l)ranches on the lower portion of the stem ; those on the summit appear at 

 first to form a regular dichotomy, otherwise the description of one such on page 15 is 

 sufficiently exact. The spicular covering on the stem is very easily rubbed ofi". 



Melitodes fragilis, n. sp. (vide p. 180). 



Since the description of this species was printed, a nearly complete specimen was 

 found in a case containing species of Alcyonaria from the Bay of Amboina. 



The species proves to be of larger dimensions than, from the fragments first 

 discovered, had been surmised. 



The colony, of which a portion only has been preserved, arises from a much 

 branched base probably attached to dead corals ; from it numerous branches proceed in 

 an irregularly dichotomous manner, forming a series of somewhat parallel f:m-shapcd 

 structures, which anastomose with one another and which arise at an acute angle from 

 the basal part. 



The internodes are short and stumpy at the base, gradually becoming longer 

 towards the free extremities.
